To support the yoke in a horizontal position, l provide two Iixeditracks fixed to the side members 13 and supporting the end portions ofthe yoke againstfdownward die placement, the yoke being slidable on the ttraeks.

`Supported by one of the transverse niem- `-"bers"l4 is-a -lixedhheafd rest preferablyl com- 15 posed of a "leatheri casing 2*( 1 and a com pressible iilling 28 of curled-hair.
